Title: Measurement of the isolated di-photon cross-section in $p p$ collisions at $\sqrt{s} = 7$ TeV with the ATLAS detector

Abstract

CERN-LHC. The ATLAS experiment has measured the production cross-section of events with two isolated photons in the final state, in proton-proton collisions at sqrt(s) = 7 TeV. The full data set acquired in 2010 is used, corresponding to an integrated luminosity of 37 pb-1. The background, consisting of hadronic jets and isolated electrons, is estimated with fully data-driven techniques and subtracted. The differential cross-sections, as functions of the di-photon mass, total transverse momentum and azimuthal separation, are presented and compared to the predictions of next-to-leading-order QCD.

Measurement of the inclusive isolated prompt photon cross section in $p p$ collisions at $\sqrt{s} = 7$ TeV with the ATLAS detector

Dataset Aad, G. ; The ATLAS collaboration

CERN-LHC. Measurement of the cross section for inclusive production of isolated prompt photons in proton-proton collisions at a centre-of-mass energy of 7 TeV. The measurement covers the |pseudorapidity| ranges < 1.37 and 1.52 to 1.81 for photons of transverse energy from 15 to 100 GeV from a data sample of total integrated luminosity of 880 nb-1. The isolation criteria is based on the energy in a cone (R=0.4) in pseudorapidity-azimuthal angle space around the photon direction.

Measurement of the inclusive isolated prompt photon cross-section in $p p$ collisions at $\sqrt{s} =$ 7 TeV using 35 pb $^{- 1}$ of ATLAS data

Dataset Aad, Georges ; The ATLAS collaboration

CERN-LHC. Measurement of the inclusive production of isolated prompt photons in proton-proton collisions at a centre-of-mass energy of 7 TeV. The data sample used has an integrated luminosity of 35 pb-1. Photons are isolated if the total transverse energy in a cone (in phi,eta space) of radius R=0.4 is less than a cut value of 4 GeV. The four systematic errors shown in the tables represent, respectively, the uncertainties in (1) the purity measurment, (2) the photon selection and identification efficiency, (3) the correlation between the efficiency and purity determination and (4) the unfolding process. The luminosity uncertainty of 3.4%more » is shown separately.« less
